We mark certain days of the year with ‘On This Day’ posts, recalling events associated with them.

Our events are grouped under two calendars. The Gregorian ‘New Style’ (NS) is the worldwide calendar first issued at Rome in 1582. On that calendar, today is December 18. The Julian ‘Old Style’ (OS), also issued at Rome but in 46 BC, was used in Roman Britain and then in England from Anglo-Saxon times until 1752. It is still used today by roughly 100 million Orthodox Christians worldwide. On that calendar, today is December 5.

Fiery young attorney Thomas Erskine stood up in the House of Commons to denounce a bill aiming to silence critics of the Government.

In December 1795, the Seditious Assemblies Act was passed in Westminster. Aimed at snuffing out sympathy for the French Revolution, the Act banned critics of the King, the Constitution or even Government policy from airing their views in public without prior permission. William Belsham recorded that crusading lawyer Thomas Erskine, MP for Portsmouth, had reacted angrily at this travesty of English liberties.
